I'll second that. I've been considering a new release of Photuris, in
honor of its upcoming 10th anniversary, and was wondering what should be
the "best" defaults?

Or should the hash be SHA-256? Or is RIPEMD still going strong?
I've seen a number of messages disparaging MD5 as possible to be broken
(in the next decade or so, or speculated already), but no firm
recommendations on the replacement....
Likewise, CAST versus Blowfish versus AES (Rijndael) versus ....
Now, I know when you rub 2 cryptographers together, you get (2**2)-1
opinions; but I'm getting rather tired of the continual griping without
solid recommended alternatives....
